Parents who are concerned that their children are always tired or are having difficulties concentrating should look at their media habits, scientists have said.
They claim that the more time a child spends on a computer or watching television, the more their sleep pattern is likely to be disrupted.
According to the scientists from Finland, previous studies have already suggested that the use of electronic media can affect a child's sleep. Since sleep directly affects a child's mental and physical health, including their performance in school, they decided to look into this further.
They looked at the sleep, TV viewing and computer use patterns of children aged 10 and 11. These patterns were then reassessed in the children 18 months later.
Note: Details of these findings are published in the journal, BMC Public Health.
